^This. There are a handful of games that require an overclocked 3570K at 4.2-4.5 GHz, including Super Mario Galaxy (because it requires DSP LLE to not crash/have broken audio) and F-Zero GX (because it requires Sync GPU, which is basically dual-core mode with a ludicrous amount of checks to make it behave like single-core mode while being *slightly* faster). The 3570K overclocks very well as long as you have a decent cooler on it, so there's no need to worry about how hard you're pushing it.

If you don't want to overclock it, you can disable Sync GPU for it (right-click the game > Properties, uncheck "Synchronize GPU Thread"), but be aware that this can cause the game to crash randomly. It seems to have no problem/less problems with the current OpenGL backend, though.
